format-number-entry

Format-number-entry provides a quick way to convert a string into a formatted telephone number. It also provides a way to convert an alphanumeric string into a normal phone number (eg 1-800-CALL-ATT into 1-800-225-5288).

However, this package is not limited to telephone numbers only. It will accept any string and convert it into any template that you enter.
